Sharing Experience from 24 Months of Database Upgrade and Migration
Martin Klier, Performing Databases GmbH
Sharing Experience from 24 Months of Database Upgrade and Migration Running out of support, security concerns, new features, coming operating system or hardware changes.... there is a long and versatile list of potential reasons for our customers, to change the version of their running Oracle Databases. The "choice" of situations, challenges and options for changing the version, is at least as long and as versatile as the reasons are. Oracle ACE Director Martin Klier will deliver an unveiled overview about his adventures with logical dependencies, human sensitivities, technical skulduggeries and license traps. All this happens, when one or multiple databases are to be migrated or upgraded to a new version in a controlled fashion. For A as in AIX, L like Linux, S like Solaris, V like Virtualization, W twice in Windows ... there was trouble, there was a solution, and there was a new experience!
Being in IT business as a specialist for Linux, Martin Klier has been involved in the administration of Oracle Databases for about fifteen years now. The integration of large Oracle-based high-availability solutions (MAA) with RAC and Data Guard were the first challenges. In the last years, he largely moved into performance analysis and tuning of complex systems with dynamically changing load profiles. Skeptical needs assessments, thorough architecture planning, decent system sizing, critical benchmarking and experienced load-focused system analysis are Martinâ€™s formula to success in avoiding production downtime. For years now, Martin can be found speaking on topics regarding â€œOracle Core, Performance and High Availabilityâ€ on various national and international conferences, like COLLABROATE (IOUG), Oracle Open World or DOAG Konferenz. Martin frequently blogs about recent issues and their solutions at http://www.usn-it.de and is known on Twitter as @MartinKlierDBA. Martin works a lot for the community, especially for the German Oracle Users Group â€œDOAGâ€ and Linux User Group Mitterteich, and is an Oracle ACE Director (Database).
